Hello, I have an MT6572 phone that is unable to reboot to recovery mode when pressing Power + Volume Up or Down. I can't also flash anything on Fastboot because of not support on security or security deny 0xxxx.

The only way to fix this would to reverse engineer it using something like Ghidra or Binary Ninja, but after loading up Ghidra, I realized... I don't really understand, I can search for strings and other stuff but the logic behind code, it just not for me or I just need more time. But I don't have that much time to sit and learn.

Could someone give me some tips or even fully help?

Here is what am working with:
[ Login to download]

Have a nice day

the files you attached are bootloader files only.
first download stock rom of your model and flash phone make sure download only option is selected do not do full format using format all + download.
after flashing rom you should be able to boot into recovery.

or if phone is on working
then use adb to boot to recovery if you are getting errors in adb devices try latest adb platform tool for windows or try lower versions.
if you want ro hard reset device
you can try
adb reboot bootloader
fastboot -w.
try these methods

Thanks for being first to reply, but I know all those methods, still thanks, I wanted to modify the lk so it would be easier for other people to use, including me. Also reflashing firmware does nothing.

is phone on or bricked.
first readback nvram using sp flash tool
when phone is connected then in left side tells size of userarea emmc boot 1 boot2 rpmb.note down it in notepad.
go to format tab of spft
format boot1 boot2 userarea by address saved in notepad.do not mess with rpmb.
reflash rom using format all + download
restore nvram

i don't know how to modify lk.bin but probably using hxd.why u want to do modification of bootloader files.
to turn on phone if not on then reprogramming emmc may help using box.(rpmb cleaning and writing key)
